You just never know what you’ll stumble onto when you’re out fishing—it’s not always about what’s on the line. Back in 2013, a guy from Wisconsin named Ray Groff found that out the fun way when he hauled up what looked like a 200-year-old flintlock rifle from the mud of Lake Winnebago while pulling his anchor. Kinda makes you think—something like that could turn up anywhere, even here in Montana. Whether you’re chasing rainbows in the mountain lakes or trolling for walleye on the prairie, there’s always a little mystery waiting beneath the surface.
